In some cultures and social environments, people may use code names or suggestive words to belittle the appearance of others. The following are some common ways. Although the specific forms of these expressions vary by culture, region and context, they may generally include: 1. **Animal metaphor**: Describing a person with animal characteristics, such as calling someone like a "pig" or "lion", implying a defect in body shape or appearance. 2. **Food metaphor**: Using food images, a person may be called "potato" or "cheese", which are usually used to describe a large body or lack of attractiveness. 3. **Color suggestion**: Someone is referred to as "pale" or "dull", etc., which may imply that their face lacks vitality or attractiveness. 4. **Clothing comments**: Implying that a person is not dressed properly, such as "dressed like he just came out of the garbage dump", indicating that the person's appearance and dress are not appreciated. 5. **Age suggestion**: Using statements such as "old-fashioned" or "looks older than the actual age" to belittle a person's appearance or temperament. 6. **Skills or specialties**: For example, saying someone is "not suitable for modeling" implies disapproval of their appearance. This type of derogation is usually subtle, and the use of code words and hints can avoid direct conflict, but it can also cause harm. Therefore, you should pay special attention to the words you use in communication to avoid hurting others unintentionally.
